Free International Code Council M2 Practice Exam with Questions & Answers

The IMC special exhaust provisions require exhaust outlets terminating at temperatures exceeding 600°F to be designed as a chimney , and the table language identifies this as a single-wall metal chimney . Therefore, Option D is correct.

Under the ICC administrative provisions used with the mechanical code, one approved set is retained by the code official, and one approved set is returned to the applicant. The returned set must be kept on the site of the building or job while the authorized work is in progress. That directly matches Option A . It does not require return to the architect, filing with the county clerk, or retention for one year after completion.

For a single-wall vent connector serving one appliance, the maximum horizontal length is determined from the vent connector sizing and length rules. For a 5-inch diameter connector with a 10-foot vent height , the permitted maximum horizontal length is 7.5 feet . Therefore, Option B is correct.

The ICC mechanical code requires condensate disposal components to be of approved corrosion-resistant material , and the drain line shall not decrease in size from the drain pan connection to the place of disposal. The code minimum size is 3/4 inch , so the 1/2-inch statement is incorrect, and the code is not limited to PVC only. Also, the slope requirement for horizontal drain piping is not less than 1/8 inch per foot , not 1/4 inch per foot. That makes Option A the only fully correct statement.

The IFGC requires the appliance shutoff valve to be located in the same room as the appliance and within 6 feet of the appliance . Therefore, the correct answer is A .

This item appears to use older or simplified exam wording . Current ICC language for polyethylene plastic piping identifies heat-fusion joints, electrofusion joints, and stab-type insert fittings as the named PE joining methods, not solvent cement or threaded couplings. Among the answer choices you provided, D. Compression coupling is the only choice that aligns most closely with a mechanical fitting/joining approach for PE systems, while rubber cement, solvent cement, and threaded coupling do not match ICC PE joining practice. Because of that, D is the best answer from the listed options, but this question should be tied to the exact code cycle or source exam bank if you want absolute cycle-specific certainty

The IFGC rule for above-ground outdoor piping requires piping installed outdoors to be elevated not less than 3 1/2 inches above ground , and where installed across roof surfaces, not less than 3 1/2 inches above the roof surface . Therefore, the correct answer is A .

For commercial kitchen exhaust associated with Type I hood systems, the recognized code-based minimum duct transport velocity is 1,500 feet per minute , so C is the correct answer. Option B uses the wrong unit, and the other listed velocities do not match the code minimum used for this question type.

The ICC administrative provisions require construction documents to be submitted in two or more sets with the permit application. After approval, one set is retained by the code official and one set is returned to the applicant to be kept on the job site during construction. That is exactly the condition described in Option D . The code does not state that all sets are retained by the code official or that the purpose is to provide subcontractor copies or backup copies.

For this type of continuously ventilated exhaust shaft serving a multifamily building, the code requires the kitchen exhaust connection to penetrate the shaft and extend vertically not less than 22 inches without a fire damper. That matches Option D .
